JOMBINATION OIL AND GAS BURNER.

Specification of Letters Patent. Patented Sept. 10, 1912.

Application led 'February 10, 1912. Serial No. 676,697.

To all whom it may concern:

Be it known that I, Jol-IN A. GREENERT, a citizen of the United States, residing at Hutchinson, in the county of Reno and State of Kansas, have invented certain n ew and useful Improvements in Combination Oil and Gas Burners; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art. to which 1t appertains to make and use the same, reference beingv had to the accompanying drawings,

My invention relates to combination oil and gas burners, and has for its principal object to provide a device of that character which may be used. with either oil or gas, or with both simultaneously, the device being particularly adaptable for localities where natural gas is used as fuel and where there is a probability of failure of the gas supply. In accomplishing this object I have pro vided the improved details of structure hereinafter described and illustrated in the accompanying drawings, wherein like reference numerals refer to like, parts throughout the several views, and wherein:

Figure I is a side elevation of a combination burner constructed according to my invention, the lire bowl of a stove or furnace being indicated to show the application of the burner. Fig. II is a central,y vertical section of the burner. Fig. III is a plan View of same, the dome being in section on the line IIL-III Fig. II. Fig. IV is a similar view on the line IVTIV, Fig. II. F ig. V is a plan view of the diaphragm ring used in connection with the burner for concentrating the air for mixture with the oil vapor.

Referring more in detail to the parts: l designates the fire bowl of an ordinary stove or furnace having` an inturned flange 2 on its inner face. Supported on the flange 2 is a diaphragm ring 3, preferably of sheet metal and adapted for entirelyseparating,r the fire bowl into upper and lower chambers. Supported on the ring 8 is a burner base 4, comprising a lsupporting ring 5 which rests directly on the diaphragm ring, and a vertical flange 6 which rises from thc ring 5 and 'is provided with ports 7 for the outlet of gas. At the inner periphery of ring 5 is a keeper flange 8, and supported on the base ring 5 Within the flange 8 is a drum 9 preferably constructed of cast metal and having a slightly inwardly tapering upper portion. Extending radially from the drum 9 at a suitable distance above the burner base is a hood l0 having an ou 'Awardly and downwardly sloping rim 1l which is turned horizontally at its edge to resten the` base flange G, and has a cupped rim l2 for a purpose presently set. forth. At regular intervals around the druinare partitions 13 which divide the annular chamber within hood 10 into separate compartments. The hood and partitions are preferably cast integral with the drum 9 and there are prefer ably four of the separate compartments. Opening through an aperture 14 into each of said compartments is a supply pipe 15- which may extend down through the furnace grate (the furnace 1s not shown) and is adapted for supplying gas to cach of said compartments separately and also for supporting the burner, asthe weight of the burner isv ordinarily too great tube sup ported on thc sheet metal diaphragm. EX- tending around the upper end of the drum 9 is an outer circumferential cup member 1G adapted for receiving oil from the ends of the delivery branches 17 of a supply pipe 1,8 which latter extends down through a web 19 of the burner base and through the furnace grate to a source of supply. There are preferably two of the branches 17 which extend in opposite directions and feed the' cup 1G at opposite sides of the burner. 'Supported in the cupped rim 12 of the hood l0 is a dome 20, the lower end of which is provided 'with ports 21 through `which oil or oil vapor may flow into the .outer portion ofthe run.

The dome is preferably casty and substantially semispherical in form, being separate from the body of the burner to facilitate installation.

In assembling the burner, the diaphragm is first placed on the fire bowl flange, and the, burner base placed thereon with the pipe apertures registering wit-h the apertures of the diaphragm ring. The supply pipes are then threaded into the apertures therefor in the burner base and connected with a source of supply. The drum 9 is then deposited on the burner base so that cach 'of the supply pipes l5 will open into about the center of one of the gas compartments. The oil supply pipe is then installed,

-, meagre@ pi es being provided with a` suitable` mixer (not shown), and the small compart ments confining the gas so that it is discharged under pressure that insures a proper fuel mixture.

When oil is burned, the pipe 18 is opened, and oil iows out through the branches into the trough 16 over the edge of which itiiows down the sides of vthe drum 9, over the head 10, and into the rim 12, through the dome ports 21. When the burner is hot, the oil -will of course become vaporized before it has reached the rim 12, and the vapor will ass out through the ports 21, mix with airsw ich enters through the center of the'burner and rises through the drum 9 intocontact with the curved ninner surface of the dome by which it is deflected downwardly to mix with the oil vapor. i

It is-ap arent that by running the oil supply ipe t rough the hood 9, and admitting res cool air through said hood the oil in the sup 1y pipe will be kept cooi until discharge into the hoodv trough thereby, obviating carbonizing of the oil, which carbonizing would result in stoppage of the 1 s. t p t is apparent that the 'parts of the burner are constructed to adapt the burner for they use of, either oil or gas, and that the combination for the separate fuels does not materially inereasepthe cost of the burner. It is also apparent that oil and gas. may be burned slmultaneously.

Having thus described my invention, what p I` claim as new.' therein and desire secure A by Letters-Patent is l. A burner, comprising a'vertical drum having a trough'on its outer face near its upper edge, an oil su) lY i e extendin through the interior idf) tiiep drum, ang adapted for delivering into said trough, a hood on the outside ot said drum terminating in a troughed rim, and a dome covering said drum and a part of the hood, said dome having ports in its lower edge, for the purpose set forth.

Y 2. A burner, comprising a vertical drum having a trough on its outer face near its upper edge, an oil supply pipe evtendinpr through the interior of vthe drum, an

ada ted for deliverin into said trou h, a hoo on the outside o. said drum termmating a troughed rim., and a -semi-circularl fitted on said base and having a hood porr tion supported on said ange, said hood portion being provided with a troughed grim, means for delivering o1l to the outer `sun'tace of said drum, a dome seated 1n said rimk and covering the drum and hood, and supply pipes opening through said base into said hood.

4C. A burner, comprising a base having an edge fiange provided with openings, a drum fitted on said base and having a hood portion supported on said fiange, said hood portion being provided with ra troughed rim, means for delivering oil to the outer`surface of said drum, a dome seated in said rim and coveringl the drum and hood, and supply pipes opening through said base into said hood, said hood bein divided int sep- J.
